"On my breath," said the Lion. "I will blow you into the west of the world as I blew
Eustace."
"Shall I catch him in time to tell him the first sign? But I suppose it won't matter. If he
sees an old friend, he's sure to go and speak to him, isn't he?"
"You will have no time to spare," said the Lion. "That is why I must send you at once.
Come. Walk before me to the edge of the cliff."
Jill remembered very well that if there was no time to spare, that was her own fault. "If I
hadn't made such a fool of myself, Scrubb and I would have been going together. And
he'd have heard all the instructions as well as me," she thought. So she did as she was
told. It was very alarming walking back to the edge of the cliff, especially as the Lion did
not walk with her but behind her - making no noise on his soft paws.
But long before she had got anywhere near the edge, the voice behind her said, "Stand
still. In a moment I will blow. But, first, remember, remember, remember the signs. Say
them to yourself when you wake in the morning and when you lie down at night, and
when you wake in the middle of the night. And whatever strange things may happen to
you, let nothing turn your mind from following the signs. And secondly, I give you a
warning. Here on the mountain I have spoken to you clearly: I will not often do so down
in Narnia. Here on the mountain, the air is clear and your mind is clear; as you drop down
into Narnia, the air will thicken. Take great care that it does not confuse your mind. And
the signs which you have learned here will not look at all as you expect them to look,
when you meet them there. That is why it is so important to know them by heart and pay
no attention to appearances. Remember the signs and believe the signs. Nothing else
matters. And now, daughter of Eve, farewell -"
The voice had been growing softer towards the end of this speech and now it faded away
altogether. Jill looked behind her. To her astonishment she saw the cliff already more
than a hundred yards behind her, and the Lion himself a speck of bright gold on the edge
of it. She had been setting her teeth and clenching her fists for a terrible blast of lion's
breath; but the breath had really been so gentle that she had not even noticed the moment
at which she left the earth. And now, there was nothing but air for thousands upon
thousands of feet below her.
She felt frightened only for a second. For one thing, the world beneath her was so very
far away that it seemed to have nothing to do with her. For another, floating on the breath
of the Lion was so extremely comfortable. She found she could lie on her back or on her
face and twist any way she pleased, just as you can in water (if you've learned to float
really well). And because she was moving at the same pace as the breath, there was no
wind, and the air seemed beautifully warm. It was not in the least like being in an
aeroplane, because there was no noise and no vibration. If Jill had ever been in a balloon
she might have thought it more like that; only better.
